Abstract

Aiming at the dynamic changes of network topology of UAV group in the complex environment of military confrontation, this paper proposed a lightweight dynamic key management scheme for UAV group, which solved the key update problems when the network topology changed dynamically, such as UAV joining and exiting, batch joining and exiting, group merging and splitting. When the network topology didn't change, the scheme could also provide local periodic key update to improve the efficiency of UAV group key update. By constructing a congruent system, the scheme divided the secret information into user space, free space and retract space, the user space could calculate and recover the session group key after receiving the broadcast message from KGM, but the free space and retract space couldn't calculate and recover the group key. During the key update process, KGM used idle time to select the key from the key pool in advance for predictive calculation, which reduced the delay caused by constructing broadcast messages for complex calculation. Through analysis and experiments, the scheme has forward and backward security, anti-collusion attack and node cancellation capabilities. Compared with existing UAV key management schemes, the scheme optimizes the computation and communication overhead, and the node storage overhead is small, which is suitable for the UAV group network with dynamic topological changes.
